Garden Closed

The United States Botanic Garden (USBG) is temporarily closed to the public to reduce the risk of transmitting COVID-19 coronavirus.

Whenever possible, the USBG will reschedule public programs and events originally scheduled during the closure period. Please monitor the USBG website for updates to operating status. Many resources can still be accessed online, including educational worksheets and manuals, fact sheets and more, and some of our programs will also be made available online. Find online resources at
